SAFETY-CATGH FOE PINS.

Application filed July 31, 1919.

To all whom it may concern Be it known that I, Gnonon IV. BAINTON, acitizen of the United States, residing at Providence, in the county ofProvidence and State of Rhode Island, have invented new and usefulImprovements in Safety-Catches for Pins, of which the following is aspecification.

This invention relates to certain new and useful impro ements in asafety catch for pins and it has for its primary object to provide asafety device which will function even though the same be not in itsfully operative position.

- The invention resides in a peculiarly shaped safety catch having apart disposed so as to obstruct the opening to the keeper during theinitial portion of the movement of the lock from full operative to fullinoperative position.

Further, the invention resides in the features of constructionhereinafter described and clain'ied, reference being made to theaccompanying drawing wherein Figure 1 is a bottom plan view of a bar pinequipped with the improved safety catch:

Fig. 2 is a side elevation thereof:

Fig. 3 is a transverse vertical. section through the safety catch online 33 of Fig. 2, depicting the catch fully opcratively disposed: and

Fig. I is a similar view showing the catch swung from its fullyoperative position.

The article of jewelry, or the like, to which the present invention isapplied is designated by the numeral 1 and its pin by the numeral 2,said pin having its piercing end engageable in and adapted to be securedby the safety catch.

This safety catch comprises a keeper l divided into two parts 3-3, whichare formed with registering slots 5 that extend downwardly at an inclineand open laterally. A lock or latch member 6, substantially of U-form isinterposed between the keeper parts 3-3, and pivoted thereto by a pivotpin 7 passing'through the extreme end of the outer leg or arm 8 of saidU-member.

Specification of Letters Patent.

Patented Apr. 13, 1920.

Serial No. 314,474.

This arm is provided with a projection or lift 9 extending beyond thekeeper whereby it may be engagedby the finger to effect swinging of thelock member. The opposite leg 10 of the U-member is shorter than theouter leg and is pointed. The slot of the U-member has its outer wallinclined substantially in alinement with the adjacent side wall of slot5 while the inner wall diverges slightly therefrom to afford ample roomto clear the pin when in its keeper.

The operation of the safety latch is obvious from the foregoingdescription, the

-pin being first engaged in its keeper slot while the U-block isdisposed in the dotted position of Fig. 4, after which the same is swungto tie fully closed position depicted in Fig. 3. Should the lock memberaccidentally swing or move from its full, operative position the leg 10will lie across the keeper s ot and bear against the pin to hold itfirmly in the keeper. Fig. leshows the point of the leg 10 just leavingthe pin whereby the latter is free to be withdrawn from its keeper.Because of the position of pivot 7 and the incline of slot 5, anylateral pressure on the pin will not tend to swing the lock member fromits full operation. Consequently this simply constructed safety catchcooperates with the pin to hold the former active. Furthermore alatitude of iovement is afforded the lock without rendering itinoperative.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:

1. In a pin safety catch, a keeper having an upwardly extending slottherein to receive the pin, and a substantially U shaped lock having oneleg slightly larger than the other and pivoted to the keeper adjacentthe slot whereby upon accidental release the smaller leg will 'bemaintained across the slot until the lock is positively swung past thecenter of gravity.

2. In a pin safety catch, a horizontally extending keeper having anupwardly extending inclined slot to receive the pin, a substantially Ushaped lock pivoted at one leg thereof to the keeper adjacent the slotIn testimony whereof I have signed my and adapted to be swung Within thekeeper name to this specification in the presence of to look the pinbetween the bottom Wall of two subscribing Witnesses.

the slot and the bottom Wall of the U of GEORGE W. BAINTON. 5 said lock,and the pivoted leg of said 1001: Witnesses: 7

being slightly larger than the other leg as BESSIE P. TOOMEY,
